Abstract(s)
O estudo investigou a influência do uso de lareiras residenciais sobre a concentração de
benzo(a)pireno (BaP) no ar urbano da cidade de Viseu, em Portugal. O BaP, um
hidrocarboneto aromático policíclico altamente cancerígeno, é emitido principalmente
pela combustão incompleta de biomassa. A análise foi realizada com uso de técnicas
cromatográficas, com colheita e extração de amostras atmosféricas a aplicar a
metodologia definida na norma EN 15549:2008. Os dados obtidos revelaram que os
níveis de BaP frequentemente excedem os limites legais europeus durante os meses de
inverno, a potenciar impactes negativos na saúde respiratória e cardiovascular da
população local. Os resultados indicam que a queima de lenha é uma das principais fontes
de poluição por BaP na cidade. O estudo conclui pela necessidade de políticas públicas
para uma melhor monitorização de BaP, além da substituição de sistemas de aquecimento
tradicionais por tecnologias mais limpas, bem como pela sensibilização da população
sobre os riscos associados a práticas de combustão inadequadas.
The study investigated the influence of the use of residential fireplaces on the concentration of benzo(a)pyrene (BaP) in urban air in the city of Viseu, Portugal. BaP, a highly carcinogenic polycyclic aromatic hydrocarbon, is emitted mainly by the incomplete combustion of biomass. The analysis was carried out using chromatographic techniques, with atmospheric samples collected and extracted using the methodology defined in standard EN 15549:2008. The data obtained revealed that BaP levels frequently exceed European legal limits during the winter months, potentiating negative impacts on the respiratory and cardiovascular health of the local population. The results indicate that wood burning is one of the main sources of BaP pollution in the city. The study concludes that there is a need for public policies to better monitor BaP, in addition to replacing traditional heating systems with cleaner technologies, as well as sensitising the population to the risks associated with inadequate combustion practices.
